Even if Sophie does escape the public vote this week, there is no guarantee she will be in the final next week.

It has been reported that show bosses are planning a surprise live eviction next Tuesday, meaning just five housemates will remain for the final on 4 September.

Meanwhile, David won a token for the house after brushing his teeth with cheese.

The camp clothes sorter was the first housemate to be summoned to the Diary Room for the Terrible Toothpaste task, where he was told he had to brush his teeth with potent Stinking Bishop cheese for a minute in order to pass the challenge.

Despite gagging and retching throughout the minute, the tearful fashion lover completed the task and quickly blasted Big Brother for the choice of substance.

He wailed: "Eugh, it stinks like sweaty feet. My teeth feel like absolute s**t. It's absolutely foul. How could you do such a thing."

The next housemate to undertake the task was Sophie, who failed to complete her mission of cleaning her mouth with pureed pickled catfish.

She quickly gave up on the challenge, saying: "It makes me feel sick just brushing my teeth with toothpaste. I really don't think I can do this.

"I'd rather eat dog food than this - it smells better and probably tastes better."

While David and Sophie had struggled to get to grips with their toothpaste substitutes, Charlie later complained he wished the task had been worse.
